Limp Mode, p0882 Code etc?

Hello, So the code P0882 means the transmission control circuit is seeing low voltage. If the PCM/transmission fuse is blowing, the truck is likely going into limp mode because the transmission control power feed is being lost. Also I would do a tune up for the misfire which can affect engine vacuum which can make the transmission shift late. I have seen a shorted shift solenoid cause this problem but you should look at the transmission wiring harness as well. To help check it unplug the transmission electrical connector and then replace the fuse and turn the key on to see if the fuse still bows, please let me know.
